you are close... many linguists do not count guernsey, alderney, sark and jersey french as a seperate language. However alderney and guernsey french are too diferent to be called a dialect it is like saying englsih is a dialect of german which it is no longer the case. If a french and guernsey french person were to have a conversation they definitely will not understand each other . After the war people were punished for speaking guernsey french. apparently only 200 or so can speak guernsey french. alderney french became a dead language but I still use it occasionally.

the true guernsey dialcet of englsih

yeahrah yes

weh you too weh? where are you going?

etait byo ne? how are you? (lit. you are well?)

the game playing which one eh? what game are you playing?

as you can see guernsey dialect of english has a very strong accent and it maily muddles the tenses and word order up. There is no past tense or future tense in alderney french
